Circle's CCTP (Cross-Chain Transfer Protocol) launched on Stellar, enabling native 1:1 USDC bridging across 17 blockchains. This technical walkthrough demonstrates the implementation with working code: burning USDC on one chain authorizes minting on another. Includes open source examples and testnet demo.
Circle's CCTP is now live on Stellar, providing native bridging infrastructure for USDC across 17 blockchains at 1:1 ratio. Unlike synthetic bridges or liquidity pools, CCTP uses Circle's token messenger contract to burn assets on the source chain and mint on the destination chain, eliminating slippage and counterparty risk. This video walks through a complete implementation in JavaScript, covering the bridge-in and bridge-out scripts, decimal handling across chains (Stellar's 7 decimals vs EVM's 6), contract interactions, and attestation confirmation. The speaker demonstrates the code in action on testnet, showing developers how to integrate CCTP for onboarding users and moving funds at near-zero cost.
